This case report presents a treatment of peri-implantitis associated with a pre-existing pathology. Peri-implantitis around the implant #19 was detected from pus discharge upon probing. Guided bone regeneration was performed to treat peri-implantitis with the administration of antibiotics. The histopathologic evaluation of soft tissue taken from the circumferential defect around the implant exhibited a cyst. The post-surgical CBCT and the follow-up radiograph confirmed the maturing bone graft and a reduced size of the defect around the implant...

The purpose of this Clinical Case Letter is to investigate the pattern of dental implant displacements into the mandibular marrow space and to suggest a suitable method for the removal of the displaced implants. Five patients were consulted at the authors' institute. All patients had experienced sudden displacement of an implant into the mandibular medullary cavity. Except for one female patient, no patient had a history of osteoporosis. The displaced implants were retrieved by crestal hole widening or lateral decortication...

Oral implantology has become a major discipline within the field of dentistry. Small or mini dental implants have demonstrated success in the retention of removable and fixed prosthesis. This retrospective study reports on 335 SDI placed during a 7 year period. A total of 321 implants were restored and functional within the studies time interval. A total of 14 implants failed resulting in a 96.1% implant success rate. Treatment plan considerations should include prosthetic design, specific arch and immediate load...

Socket shield technique has been accepted as a promising technique to maintain alveolar ridge contour, while the root fragment may exhibited signs of resorption. In the present case a newly modified approach which avoid the dentin-implant interface was employed to reduce adverse effects. This case report was targeted to evaluate the feasibility of this modified approach in a clinical practice setting.

Clinical decisions regarding the stability and osseointegration of mandibular implants positioned using the bone expansion techniques are conflicting and limited. The objective was to evaluate the stability of implants placed using two surgical techniques, selected according to the initial width of the mandibular posterior edentulous ridge, with D3 bone density, during a 12-week period. Fifty-eight implants in 33 patients were evaluated. Thirty-two implants in 24 patients were positioned using the osteotome expansion technique, and twenty-six fixtures in 17 patients were installed using the conventional drilling technique...

The aim of this invitro study was to evaluate the effect of implant position and edentulous span length on stresses around implants assisting claspless distal extension partial overdentures.Four bilateral mandibular distal extension acrylic models were constructed. Two implants were inserted in the distal extension ridges parallel to each other and perpendicular to the ridges. Based on the implant position, models were categorized into two groups: Group I, mesial implants position and Group II, distal implant position...

This study evaluates the load fatigue performance of different abutment-implant connection implant types—retaining-screw (RS) and taper integrated screwed-in (TIS) types under 3 applied torque levels based on the screw elastic limit. Three torque levels—the recommended torque (25 Ncm), 10% less and 10% more than the ratio of recommended torque to screw elastic limits of different implants were applied to the implants to perform static and dynamic testing according to the ISO 14801 method...

The aim of this study is to assess the increase of temperature, following laser irradiation with 810nm and 980nm and 1064nm diode laser's wavelengths, of an implant, under conditions that more closely replicate those of the human body. A 4x14mm machined surface implant was placed in a porcine rib to replicate the conductivity of heat given by the bone. A peri-implant vertical defect 2mm wide and 2mm deep, to simulate bone resorption. Two thermocouples were positioned, crestally and apically, on the implant surface...

Displacement of dental implants into the maxillary sinus is a rare complication. This article presents a case of displaced dental implant into maxillary sinus. Retrieval of the dental implant from left maxillary sinus was performed via endoscopic sinus surgery. This case highlighted a delayed referral of a 53-year old gentleman by a general dental practitioner for management of dislodged dental implant into the left maxillary antrum. The implant was dislodged during placement of healing abutment four months after implant insertion to replace missing 25...

PURPOSE: this study evaluated the effects of steam autoclave sterilization on the tensile strength of two types of resin cements used to bond customized CAD/CAM zirconia abutments onto titanium bases. METHODS: forty sets of zirconia abutments cemented to screwed titanium bases of implants analogs were divided into four groups (n = 10). Two groups were treated with a conventional chemically activated resin cement (ML - Multilink Ivoclar Vivadent) and the other two groups with a self-adhesive dual resin cement (U200 - U200 RelyX 3M ESPE)...

A retrospective review of patient records was conducted in a single private practice to evaluate the efficacy of immediately placing a novel implant design in posterior jaw locations using a flapless technique. Forty-two patients (22 males, 20 females) with a mean (SD) age of 60.2 (7.6) years (range = 31-68) presented with 1-2 non-restorable molar (maxillary = 14; mandibular = 8) or premolar (maxillary = 20; mandibular = 1) teeth compromised by periodontal disease, endodontic failure, root resorption, root fracture or severe caries...

Implant surfaces are continuously being improved to achieve faster osseointegration and a stronger bone to implant interface. This review will present the various implant surfaces, the parameters for implant surface characterization, and the corresponding in-vitro human cell-based studies determining the strength and quality of the bone-implant contact. These in-vitro cell-based studies are the basis for animal and clinical studies, and is the prelude to further reviews on how these surfaces would perform when subjected to the oral environment and functional loading...

The objective of the present study was to elucidate stability development of immediately loaded hybrid self-tapping implants inserted in the posterior maxilla. Forty-eight hybrid self-tapping implants with a chemically modified surface (∅4.1; length 8 mm) were inserted bilateral in the maxillary 1st and 2nd premolar and 1st molar sites of eight patients. In each patient, both sides of maxilla were randomly assigned to either immediate (IL) or early (EL) loading group. Implant stability was evaluated by means of resonance frequency analysis immediately after implant placement and after 1, 2, 3, 4, 5, 6, 12, 26 and 52 weeks...

The recently popularised socket shield technique involves intentional retention of a thin buccal section of the remnant root at the time of immediate implant placement to preserve the buccal crestal bone from resorption. The objective of this systematic review was to assess the literature available on the socket-shield technique and weigh its biological plausibility and long-term clinical prognosis. A Systematic Search was performed in PubMed-Medline, Embase, Web of Knowledge, Google Scholar and Cochrane Central for clinical/ animal studies up to May 2016 without restrictions of language, duration, and follow-up...

This study focuses on the fatigue behavior and bone-implant attachment for the more usual surfaces of the different CP-titanium dental implants. The implants studied were: as-received (CTR), acid etching (AE), spark-anodization (SA), and with a grit-blasted surface (GB). Residual stresses were determined by means of X-ray diffraction. The fatigue tests were carried out at 37°C on 160 dental implants, and the stress-failure (S-N) curve was determined. The fatigue tests showed that the grit-blasting process improved fatigue life...

This in vitro study evaluated the effect of different levels of preparation of an implant abutment on its fracture resistance. The study evaluated abutments that incorporated a platform switch (Myriad Plus Abutments, Morse Taper Connection) and Standard abutments (BioHorizons Standard Abutment, BioHorizons Inc). Each abutment was connected to an appropriate implant and mounted in a self-cured resin base. Based on the abutment preparation depths, 3 groups were created for each abutment type: as manufactured, abutment prepared 1 mm apical to the original margin, and abutment prepared 1...
